In a large bowl, beat together the butter and sugars until well mixed.
Beat in the dry pudding mix.
Beat in the eggs, vanilla and mashed banana.
In a separate bowl, combine the flour, baking soda and baking powder. Stir to mix.
Combine the dry ingredients into the wet ingredients. Beat just until mixed.
Stir in 2 cups of the milk chocolate chips. Set the last cup of chocolate chips aside for later.
Line a cookie sheet with a silicone baking mat and scoop cookies into 2-tablespoon sizes (you'll get about 3 dozen cookies from this recipe).
Using the remaining cup of chocolate chips, press chocolate chips into the top of each unbaked cookie.
Bake for 15-17 minutes (until bottom of cookies are a light golden brown and tops of cookies still look light and soft). Once cookies are removed from oven, leave them on the cookie sheet to cool for 5 minutes before placing them on a wire rack to cool completely.
